I started with 100 because I knew that 8378 is bigger than 7500. I knew that there is only 750 in 800 so I could use 10 here. 2X 75 is 150 which is bigger than 128 so I go with 1 here.

I know that 2X43 is 86 so I can use 200 this time. Add this column up to get the answer. Don’t forget the remainder! I go with times 100 because I want to make it simple. 478 is close to 430 so I can use 10 X 43.
